What happens when your immune system attacks your nervous system?
Guillain-Barré syndrome is a rare but serious autoimmune disorder in which the immune system attacks healthy nerve cells in your peripheral nervous system (PNS).
This leads to weakness, numbness, and tingling, and can eventually cause paralysis..
Can you have a virus in your brain?
Encephalitis (en-sef-uh-LIE-tis) is inflammation of the brain. There are several causes, but the most common is a viral infection. Encephalitis often causes only mild flu-like signs and symptoms — such as a fever or headache — or no symptoms at all. Sometimes the flu-like symptoms are more severe.
Does the flu attack your nervous system?
Although our immune system creates antibodies to fight the flu virus, sometimes these antibodies can also attack the myelin or protective sheath around nerves. This condition is commonly known as the Guillain-Barré syndrome or GBS. It is a rare condition in which a person’s immune system attacks the peripheral nerves.
What does brain swelling feel like?
Symptoms of brain swelling include headache, dizziness, nausea, numbness or weakness, loss of coordination or balance, loss of the ability to see or speak, seizures, lethargy, memory loss, incontinence, or altered level of consciousness.
What virus attacks the nervous system?
Viruses that infect the central nervous system (brain and spinal cord) include herpesviruses (see also herpes simplex virus infections), arboviruses, coxsackieviruses, echoviruses, and enteroviruses.
What viruses cause neurological problems?

Can viruses trigger mental illness?
Viruses that have been associated with schizophrenia and other chronic mental illnesses such as bipolar disorder, MDD, and autism include but are not limited to influenza viruses; human endogenous retroviruses; and the herpesviruses, such as cytomegalovirus, Epstein-Barr virus, and herpes simplex virus.
Can flu affect the brain?
The infections also activated the brain’s immune cells in this region for an extended period and altered the expression of genes implicated in disorders including depression, autism and schizophrenia. These findings suggest that some strains of the flu may pose a threat to healthy brain function.
How does a viral infection make you feel?
Often, a person will experience symptoms that may include a runny nose, coughing, nausea, fatigue, and body aches. While not every person experiences a fever when they have a virus, a fever can be a sign that the body is trying to fight off the infection.
Can a viral infection affect your nerves?
Viral Infections Viruses may reach the brain either through the bloodstream or, in the case of rabies, by spreading along the peripheral nerves. The diseases caused by viral infections can be grouped into two categories — acute diseases and chronic diseases.
Does a virus have a nervous system?
The Central Nervous System viral diseases are caused by viruses that attack the CNS. Existing and emerging viral CNS infections are major sources of human morbidity and mortality….Central nervous system viral diseaseSpecialtyNeurology/infectious disease
What viruses affect the brain?
Encephalitis is most commonly due to viruses, such as herpes simplex, herpes zoster, cytomegalovirus, or West Nile virus. It can occur in the following ways: A virus directly infects the brain. A virus that caused an infection in the past becomes reactivated and directly damages the brain.
Can the flu cause neurological problems?
Influenza can be associated with various neurologic problems: encephalopathy (a state of confusion), seizures, neuropathy, as well as others. These complications most frequently occur in children, although cases of neurologic illness associated with adult influenza certainly occur.
What is severe nerve damage?
Peripheral neuropathy, a result of damage to the nerves outside of the brain and spinal cord (peripheral nerves), often causes weakness, numbness and pain, usually in your hands and feet. It can also affect other areas of your body.
Can a viral infection affect the brain?
viral infections – several common viruses can spread to the brain and cause encephalitis in rare cases, including the herpes simplex virus (which causes cold sores and genital herpes) and the chickenpox virus.
What does a brain infection feel like?
Symptoms associated with bacterial meningitis can include severe headache, neck stiffness, high fever, nausea, vomiting, pain or discomfort when looking at bright lights, sleepiness, and confusion.
Can a viral infection cause a stroke?
Several risk factors, including influenza A virus infection, trigger stroke. It has been shown that seasonal variation in stroke incidence closely resembles the occurrence of respiratory tract and influenza virus infections.
Is Radiculitis caused by a viral infection?
Herpes zoster radiculitis or cranial neuritis (shingles) results from a reactivation of varicella-zoster virus infection. After primary infection, the virus becomes latent in sensory ganglia. More than 90% of adults are seropositive for antibodies against varicellazoster virus.
